Millisecond pulsars and pulsar wind nebulae as sources of gamma rays and cosmic rays
(North-West University, 2008)Our main aim was to implement a fully 3D General Relativistic (GR) frame-dragging polar cap (PC) millisecond pulsar (MSP) model as a numerical code, and constrain it using multiwavelength and cosmic-ray data. We also ... -
Modelling the evolution of pulsar wind nebulae
(2014)This study focusses on modelling important aspects of the evolution of pulsar wind nebulae using two different approaches. The first uses a hydrodynamic model to simulate the morphological evolution of a spherically-symmetric ... -
A search for optical counterparts of the complex Vela X system
(North-West University (South Africa) , Potchefstroom Campus, 2012)The pulsar wind nebula (PWN) associated with the Vela pulsar, Vela X, is a complex system visible in radio, X-ray and y-ray wavelengths, but not in the optical wavelength. Knowledge of the brightness and structure of the ... -
Spatially-dependent multi-wavelength modeling of pulsar wind nebulae
(North-West University (South Africa), Potchefstroom Campus, 2020)The next era of ground-based Cherenkov telescope development will see a great increase in both quantity and quality of γ-ray morphological data. This initiated the development of a spatio-temporal leptonic transport code ... -
Spectral modelling of H.E.S.S.- detected pulsar wind nebulae
(North-West University (South Africa), 2016)In the last decade, ground-based Imaging Atmospheric Cherenkov Telescopes have discovered about 175 very-high-energy (VHE; E > 100 GeV) gamma-ray sources, with more to follow with the development of H.E.S.S. II and CTA. ...
